How Your Thyroid Could Be Working Against Your Heart

Posted 31 Oct 2017 by Drugs.com

TUESDAY, Oct. 31, 2017 – The tiny thyroid gland could have a big impact on heart health, new research suggests. Middle-aged and older adults with an elevated thyroid hormone may be at higher risk of heart disease and death, researchers found. In the new Dutch study, high and even high-normal levels of a hormone called free thyroxine (FT4) doubled the odds of having calcification of the coronary arteries. This can be a sign of atherosclerosis, commonly called hardening of the arteries. Higher FT4 levels were also linked to an 87 percent greater risk of having a heart attack or stroke and twice the risk of dying from one. "High FT4 is indicative of an overactive thyroid," explained lead researcher Dr. Arjola Bano, of Erasmus University in Rotterdam. FT4 is produced in the thyroid gland at the front of the neck. It helps control the body's rate of energy use, she said. Atherosclerosis ... Read more

Thyroid Problems May Make Things Worse for Dialysis Patients

Posted 14 Jul 2017 by Drugs.com

THURSDAY, July 13, 2017 – Poor thyroid function may diminish kidney dialysis patients' health and quality of life, a new study suggests. Hypothyroidism – a condition in which the thyroid gland does not produce enough thyroid hormone – is common in dialysis patients, but how it affects them has been unclear. Dialysis is treatment for kidney failure, where patients need a machine to filter their blood of wastes, salts and extra fluids. This study included 450 dialysis patients who completed questionnaires every six months and had their thyroid function assessed. Poor thyroid function was associated with poorer health-related quality of life, including low energy, increased fatigue, reduced physical function and greater pain. "Given the high prevalence of thyroid dysfunction and low levels of quality of life in dialysis patients, future research is needed to determine the underlying ... Read more

Know the Signs of Thyroid Trouble

Posted 24 May 2017 by Drugs.com

WEDNESDAY, May 24, 2017 – When your thyroid isn't working properly, it can cause a lot of problems. It's important to understand what your thyroid does and to be aware of signs that can signal a health issue. The thyroid is a small gland located near the base of your neck. Its primary job is to produce the hormones that control many bodily functions, including how fast you burn calories and how fast your heart beats. If your thyroid produces too many hormones, your metabolism quickens. This problem, called hyperthyroidism, can cause symptoms like anxiety and irritability, weight loss and a rapid heart beat. You may have muscle weakness or trembling in your hands or fingers. Hypothyroidism is when your thyroid doesn't produce enough hormones. You might feel tired or sluggish and even depressed. You might experience weight gain, muscle weakness and possibly constipation. In either case, ... Read more

High Thyroid Hormone Levels Tied to Stiffer Arteries

Posted 4 Apr 2017 by Drugs.com

TUESDAY, April 4, 2017 – Middle-aged and older folks with elevated levels of a thyroid hormone may face a higher risk of developing hardened blood vessels, a new Dutch study suggests. Hardened blood vessels (atherosclerosis) develop when plaque builds up on blood vessel walls. This condition is a risk factor for heart disease. "Coronary heart disease and stroke remain a leading cause of mortality worldwide, despite advances in prevention and treatment," study author Dr. Arjola Bano said in a news release from The Endocrine Society. Therefore, identifying additional modifiable risk factors for hardened blood vessels is important, he said. "These findings suggest that thyroid hormone measurement can help identify individuals at risk for atherosclerosis, and may have future implications for the prevention of atherosclerotic morbidity and mortality," Bano said. He's a doctoral candidate at ... Read more

Check Your Neck for Thyroid Abnormalities

Posted 26 Jan 2017 by Drugs.com

THURSDAY, Jan. 26, 2017 – Regular self-exams play an important role in early detection of thyroid disease, a specialist says. That's a timely reminder because January is Thyroid Awareness Month. "The number of cases of thyroid cancer is rising, and while in most cases the outcomes of treatment are favorable, some patients present with disease that has progressed and may be more difficult to treat," said Dr. Ilya Likhterov. He is an ear, nose and throat doctor in New York City. About 200 million people worldwide have thyroid disease. Of more than 20 million Americans with thyroid disease, only four out of 10 know they have it, according to the American Thyroid Association. "While in most patients thyroid cancer develops without signs or symptoms, patients who have had significant exposure to radiation or who have first-degree family members with a history of thyroid cancer need to be ...

Can You Blame Your Headaches on Your Thyroid?

Posted 2 Oct 2016 by Drugs.com

THURSDAY, Sept. 29, 2016 – People with migraines and other headache disorders have a greater risk of a thyroid disease known as hypothyroidism, a new study suggests. Hypothyroidism occurs when the body doesn't produce sufficient amounts of thyroid hormone. This can cause mood swings, weight gain, hair loss, fatigue, constipation and irregular menstrual cycles, according to researchers at the University of Cincinnati College of Medicine. The study included more than 8,400 people. The volunteers were followed for 20 years as part of a medical monitoring project. People with pre-existing headache disorders – such as cluster or tension headaches – had a 21 percent higher risk of hypothyroidism, the investigators found. And people with a possible migraine disorder had a 41 percent greater risk. The findings suggest that people with migraines are particularly susceptible to hypothyroidism. ... Read more

Thyroid Levels in High-Normal Range May Be Linked to Cardiac Arrest

Posted 6 Sep 2016 by Drugs.com

TUESDAY, Sept. 6, 2016 – People with higher levels of thyroid hormone in their bloodstream may be at greater risk of sudden cardiac death, even if those levels aren't abnormally high, a new study suggests. "Our study shows that the risk of sudden cardiac death increases with higher thyroid hormone levels, even in the normal range," said lead researcher Dr. Layal Chaker, a research fellow in endocrinology and epidemiology at Erasmus University Medical Center Rotterdam in the Netherlands. Sudden cardiac death occurs when a person's heart stops due to a malfunction in the electrical system that drives the heartbeat. Researchers found that people with thyroid hormone levels at the high end of the normal range were 2.5 times more likely to die from sudden cardiac death, compared with people at the lower end of the range. In addition, the 10-year risk of sudden cardiac death was four times ... Read more

Thyroid Cancer Cases in U.S. Level Off, Perhaps Reflecting Diagnostic Changes

Posted 15 Apr 2016 by Drugs.com

THURSDAY, April 14, 2016 – Fewer thyroid cancers are diagnosed in the United States now than in the recent past, perhaps signaling a change in physician practices, a new study says. And many thyroid growths won't even be called "cancer" any more, according to another new report. The tripling of thyroid cancer cases over the past 30 years "used to be a mystery," said Dr. Luc Morris, lead author of a report published online April 14 in the journal JAMA Otolaryngology--Head & Neck Surgery. But recently, many researchers attributed the rise largely to technological advances that allow doctors to identify and biopsy small, harmless nodules in the thyroid gland, said Morris. He is a surgical oncologist at Memorial Sloan Kettering Cancer Center in New York City. "Up to 30 percent of healthy persons have small cancers in their thyroid glands, and nearly all of these would not go on to cause ... Read more

Overactive Thyroid Linked to Breast Cancer Risk

Posted 12 Feb 2016 by Drugs.com

THURSDAY, Feb. 11, 2016 – Women who have an overactive thyroid gland might be at greater risk for breast cancer, a new study suggests. A team of Danish researchers found that women with the condition – called hyperthyroidism – appeared to face an 11 percent increase in their risk for breast cancer, compared to women with a normal-functioning thyroid gland. On the other hand, women with the opposite problem – a condition called hypothyroidism, where abnormally low levels of thyroid hormones are produced – saw their risk for breast cancer dip 6 percent below that of women with normal thyroids. But at least one breast cancer expert not involved with the study said she was reluctant to read too much into the study findings. The findings stem from a 36-year review that identified nearly 80,000 Danish women with an overactive thyroid and more than 61,000 women with an underactive ... Read more

Surgeon's Experience Tied to Success of Thyroid Removal: Study

Posted 8 Oct 2015 by Drugs.com

THURSDAY, Oct. 8, 2015 – Patients who undergo thyroid removal may be less likely to suffer complications if their surgeon performs many such surgeries each year, a new study says. Removal of the thyroid gland, located at the base of the neck, is a common operation. More than 72,300 total thyroidectomies are performed in the United States annually, usually to treat thyroid cancer or benign thyroid diseases, the study authors said. The authors examined data from nearly 17,000 American adults who had their thyroid removed between 1998 and 2009. About half these patients had cancer, and the other half had thyroid disease. Overall, 6 percent of the patients had complications after their surgery, such as damage to voice box nerves, excessive bleeding, poor wound healing, breathing or heart problems, hormone deficiency and death. Complication rates were 4 percent among patients whose surgeon ... Read more

Even Slightly Overactive Thyroid Linked to Higher Fracture Risk

Posted 26 May 2015 by Drugs.com

TUESDAY, May 26, 2015 – Even people who only have a mildly overactive thyroid gland face an elevated risk for fractures in the hips or spinal area, a new review suggests. "Subclinical hyperthyroidism" is a condition in which an overactive thyroid gland produces too much of the hormones that control basic metabolism but there is a lack of symptoms, and hormone readings are normal in blood tests. Past research has shown that more pronounced cases of hyperthyroidism are associated with a raised fracture risk, the reviewers explained. But it hasn't been entirely clear whether the same holds true for milder forms of the condition. The Swiss reviewers looked at 13 past studies involving more than 70,000 patients to try to answer that question. "There have been several studies that have previously suggested an increased risk for fractures, but up until now it wasn't clear if it was a real ... Read more

Thyroid Trouble May Harm Women's Fertility, Study Finds

Posted 26 Jan 2015 by Drugs.com

MONDAY, Jan. 26, 2015 – A new study supports the notion that thyroid disorders can cause significant reproductive problems for women. The report's authors believe that testing for thyroid disease should be considered for women who have fertility problems and repeated early pregnancy loss. The research, published Jan. 23 in The Obstetrician & Gynaecologist, found that 2.3 percent of women with fertility problems had an overactive thyroid (hyperthyroidism), compared with 1.5 percent of those in the general population. The condition is also linked with menstrual irregularity, the researchers said. "Abnormalities in thyroid function can have an adverse effect on reproductive health and result in reduced rates of conception, increased miscarriage risk and adverse pregnancy and neonatal outcomes," said study co-author Amanda Jefferys in a journal news release. She is a researcher from the ... Read more

Thyroid Problem Can Lead to Sick Leaves From Work, Study Finds

Posted 17 Jun 2014 by Drugs.com

TUESDAY, June 17, 2014 – People with an overactive thyroid gland – called hyperthyroidism – are more likely to take extended sick leave from work than those without the disorder, new research finds. This is particularly true the first year after a person is diagnosed with hyperthyroidism, according to the study published June 17 in the Journal of Clinical Endocrinology & Metabolism. The thyroid is located in the front of the neck and secretes hormones that regulate the body's energy use, oxygen consumption and heat production. The most common cause of hyperthyroidism is an autoimmune disorder called Grave's disease, in which the immune system attacks the thyroid gland. People with Grave's disease can develop eye problems and swelling of the thyroid gland, known as a goiter. In the new study, researchers analyzed sick leave and disability pension claims among 862 workers in Denmark ... Read more

Could Thyroid Activity Raise Depression Risk in Seniors?

Posted 20 Feb 2014 by Drugs.com

THURSDAY, Feb. 20, 2014 – Older adults with slightly elevated thyroid activity may be at increased risk for depression, a new study indicates. Researchers analyzed data from more than 1,500 people, average age 70, who were depression-free and had their thyroid activity assessed at the start of the study. Over eight years of follow-up, people with thyroid glands that were more active than average – but still within the normal range – were more likely to develop depression than those with lower levels of thyroid activity within the normal range, the investigators found. "These results provide insight into the powerful effects thyroid activity can have on emotions and mental health," Dr. Marco Medici, of the Erasmus Medical Center in the Netherlands, said in a news release from the Endocrine Society. Hormones produced in the thyroid gland control the rate of many bodily activities. ... Read more

Mild Hyperthyroidism Tied to Higher Death Risk

Posted 3 May 2013 by Drugs.com

FRIDAY, May 3 – People with a mild form of hyperthyroidism may be at increased risk of death from cardiovascular disease and other causes, according to a new study. Hyperthyroidism means that the thyroid gland makes and releases too much thyroid hormone, causing symptoms such as weight loss, higher blood pressure and nervousness. A mild form of the condition is called subclinical hyperthyroidism. In this study, researchers looked at about 6,200 people in Denmark who were diagnosed with subclinical hyperthyroidism between 2000 and 2009 and found that they had a significantly increased risk of dying from cardiovascular disease and other causes. Of the 706 deaths among people with subclinical hyperthyroidism, 15 percent could be attributed to the thyroid condition, according to the study, which is scheduled for presentation at the European Congress of Endocrinology, held April 27 to May 1 ...
